3.12-ck2, BFS 0.444

Here is an updated BFS patch, version 0.444:

3.12-sched-bfs-444.patch

And an updated ck tagged 3.12-ck2 patch:

3.12-ck2

The changes in this release, compared to version 0.443 and ck1 are the 2 extra patches I posted in my last announce which were designed to address various suspend to ram/disk and resume problems as discussed in previous posts. Thanks to the various people who posted bug reports and tested experimental patches along the way.

Being an even number, this is clearly a more stable patch than the last one ;)

Enjoy!

Suspend fixes for BFS 443

Investigating the hibernate/suspend/resume problems I discovered a fix that is necessary in BFS443. These changes have nothing to do with the experimental patches I've posted so if you have applied any of those you will have to roll back to BFS443 or 3.12-ck1 to apply this patch since it affects the same code. Hopefully these changes actually address the suspend issues people are having and the workarounds in the experimental patches won't be required - note that you will not be able to apply any of the experimental patches on top of this:

EDIT: Added an updated bindzero patch; apply in this order:
01 bfs443-suspend-fixes.patch
02 bfs443-bindzero.patch

Those with hibernate/resume issues please report back so I know what more needs to be done on top of this code.

New experimental hibernate patch for BFS443

Here's a new experimental patch for BFS443 for those having suspend/resume issues. Please try it out on top of BFS443 or 3.12-ck1 (discard the old experimental patch). This builds on the idea users submitted for affining tasks to CPU0 as CPUs go offline.

Experimental hibernation patch for BFS 443

In response to the numerous reports of problems with hibernate AKA suspend to disk, here is a purely experimental patch to apply to bfs443/3.12-ck1 to attempt to address the problem.

bfs443-hibernate_test.patch

Please test and report back!
